- Description: Martins Creek Power Plant is a two-unit, 1,710-MW natural-gas plant in Bangor, Pennsylvania, in the PJM-PPL market. Units 3 and 4 are natural-gas steam turbines that can also burn oil; they entered service in October 1975 and March 1977, respectively. Talen Energy reports 100% ownership. PPL’s competitive energy business, including its Pennsylvania plants, was spun off on June 1, 2015 and combined with Riverstone generation assets to form Talen Energy; this was a corporate spinoff and combination rather than a disclosed standalone plant sale. EIA lists both generators for planned retirement in June 2035. — Martins Creek Power Plant - Talen Energy · confidence: medium

## Data quality

- Reported capacity varies by source and reporting period: Talen lists 1,710 MW, SEC fleet tables list approximately 1,700–1,708 MW, and EIA lists 850 MW for each generator. The June 2035 date is an EIA planned-retirement listing for Generators 3 and 4, not a record of completed retirement. The $290 million figure relates to refinancing and should not be treated as Martins Creek acquisition or sale consideration. The facility is marketed primarily as a natural-gas plant, but the two steam turbines are documented as capable of using natural gas, residual fuel oil, and distillate fuel oil. Generator 4 is reported as having no completed uprate or derate; no separate repowering milestone is identified in the cited records.
